aws-sdk s3上传无法通过摩卡测试进行 [英] aws-sdk s3 upload not working from mocha test

问题描述

尝试通过Mocha测试运行s3上传:

Trying to run s3 upload from a mocha test:

'use strict';

describe('S3 test', function() {
    it.only('S3 test 1', function*() {
        var AWS = require('aws-sdk');
        //AWS.config.region = 'us-west-2';
        var s3 = new AWS.S3({
            params: { Bucket: 'test-1-myBucket', Key: 'myKey' }
        });
        s3.createBucket(function(err) {
            if (err) {
                console.log("Error:", err);
            } else {
                s3.upload({
                    Body: 'Hello!'
                }, function() {
                    console.log("Successfully uploaded data to myBucket/myKey");
                });
            }
        });
    });
});

但没有任何反应，它根本没有发送http请求.为什么会这样?

but nothing happens, it is not sending the http request at all. Why is that?

推荐答案

Doh.它是异步的，因此我需要使用完成的回调:

Doh. Its asynchronous so I need to use the done callback:

'use strict';

describe('S3 test', function() {
    it.only('S3 test 1', function(done) {
        var AWS = require('aws-sdk');
        //AWS.config.region = 'us-west-2';
        var s3 = new AWS.S3({
            params: {
                Bucket: 'mkruk-myBucket',
                Key: 'myKey'
            }
        });
        s3.createBucket(function(err) {
            if (err) {
                console.log("Error:", err);
                done();
            } else {
                s3.upload({
                    Body: 'Hello!'
                }, function() {
                    console.log("Successfully uploaded data to myBucket/myKey");
                    done();
                });
            }
        });
    });
});
